Sorry, udevinfo accepts only one sysfs path for one specific device,
not a list what xargs expects.
There are no options besides this one argument.
"./udevinfo /sys/class/usb/lp0" should work, but it seems that it
doesn't get the information you looking for.
I don't have any usb printer, what does:
"tree /sys/class/usb"
"tree /sys/devices/pci0000:00/0000:00:02.0/usb1"
print on your machine?
thanks,
